A Complete Guide to Bike Sizes

Foreword: Not all bike sizes are the same

Each type of bike has a specific frame and often uses a different size scale. For example, a road bike with a 54cm frame might be considered a medium size by one brand, but a large by another.

Bicycle adjustment margins

Some types of bikes, like gravel bikes, offer a wide range of adjustments, adapting to different body types. Other models, however, have limitations in this regard. This is an important aspect to consider.

How to use size charts

We've created a simple guide to help you find the right bike size:

Size Charts: Find Your Perfect Bike

Gravel and road bikes

Sizes are based on the length of the top tube (in cm), which determines the reach of the bike.

Cut	Recommended height	Horizontal tube length
XS	Up to 157 cm	48-50 cm
S	157-167 cm	50-53 cm
M	168-178 cm	53-56 cm
THE	178-185 cm	56-58 cm
XL	Over 185cm	58-62 cm

For gravel, measurements may vary slightly due to different geometries, but remain similar.

Mountain bike

MTBs are measured in inches, based on the seat tube.

Cut	Recommended height	Size (in inches)
XS	Up to 157 cm	14"-16"

M	168-178 cm	16"-19"
